Configuring a RAID array
Configuring a RAID array applies to a blade server in which disk drives or solid-state drives are
installed.
Disk drives and solid-state drives in the PS703 or PS704 blade server can be used to implement and
manage various types of RAID arrays in operating systems that are on the ServerProven list. For the
blade server, you must configure the RAID array through "smit sasdam," which is the SAS RAID Disk
Array Manager for AIX. The AIX Disk Array Manager is packaged with the Diagnostics utilities on the
Diagnostics CD. Use "smit sasdam" to configure the disk drives for use with the SAS controller. For more
information, see "Using the Disk Array Manager" in the Systems Hardware Information Center at
http://publib.boulder.ibm.com/infocenter/systems/scope/hw/index.jsp?topic=/p7ebj/
sasusingthesasdiskarraymanager.htm.
Important: Depending on your RAID configuration, you might have to create the array before you install
the operating system in the blade server.
Before you can create a RAID array, you must reformat the drives so that the sector size of the drives
changes from 512 bytes to 528 bytes. If you later decide to remove the drives, delete the RAID array
before you remove the drives. If you decide to delete the RAID array and reuse the drives, you might
need to reformat the drives so that the sector size of the drives changes from 528 bytes to 512 bytes.
Updating IBM Director
If you plan to use IBM Director to manage the blade server, you must check for the latest applicable IBM
Director updates and interim fixes.
To install the IBM Director updates and any other applicable updates and interim fixes, complete the
following steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure might vary slightly from
what is described in this procedure.
1. Check for the latest version of IBM Director:
a. Go to the IBM Director download site at http://www.ibm.com/systems/management/director/
downloads.html.
b. If the drop-down list shows a newer version of IBM Director than the version that comes with the
blade server, follow the instructions on the Web page to download the latest version.
2. Install IBM Director.
3. Download and install any applicable updates or interim fixes for the blade server:
a. Go to the IBM Support site at http://www.ibm.com/systems/support/.
b. Under Product support, click BladeCenter.
c. Under Popular links, click Software and device drivers.
d. Click BladeCenter PS704 and PS703 to display the list of downloadable files for the blade server.
